From: Patterns and predictors of exercise behavior during 24 months of follow-up after a supervised exercise program during breast cancer chemotherapy

  1. Resistance = meeting resistance exercise guideline only; Aerobic = meeting aerobic exercise guideline only; Neither = meeting neither exercise guideline; Combined = meeting both exercise guidelines; TPB = theory of planned behavior, OR represents the change in the odds of a meeting a guideline for a one-unit change in the variables
